ZWO EAF 5V Electronic Automatic Focuser
ZWO Electronic Automatic Focuser (EAF)
All Star Telescope's Take
The 5V EAF (ZWO-5V-EAF) automatically focusses your telescope for planetary and deep-sky imaging, while only connected to a 5V USB-port. The EAF has several accessories available for it including a temperature sensor, a hand controller, and adapters for a number of optical tubes. The EAF works seamlessly with other ZWO products, the ASIAIR will even allow you to control it with your phone. These are a great device for new and experienced astrophotographers.
The EAF has a few accessories available for it. The three that we really like pairing it with are:
1. The EAF Hand Controller will allow you to remotely adjust the focus of your telescope.
2. The Temperature Sensor for the ZWO EAF lets you automatically refocus based on changes in temperature.
3. The ZWO ASIAIR isn't specifically an accessory for the EAF, but it does allow for easy integration and management of the EAF in your imaging system.
These accessories can help you get the very best out of the ZWO EAF.
This is the current version of the EAF. It no longer requires a dedicated 12V power supply. Now you can directly connect it to your camera, laptop or ASIAIR via the USB 2.0 port and use a cable for both data transmission and power supply! This makes the cable management much easier, as well as reducing the need for additional power outlets.
The innovative decorative pattern on the EAF is inspired by the changes of Airy disk during focusing showing how the focusing curve gives a local minimum at best focus – giving an easy explanation on how the EAF works just with a glance on the cover!

Why buy from All-Star Telescope
We like to say that we’re the biggest astronomy shop in Canada, which is a little like bragging about being the tallest dwarf. The reality is that we’re a small, Canadian owned, family run business.
We hold a large volume of inventory in our Edmonton warehouse, and ship daily. We ship to the USA and globally, and it's worth noting that there is no duty on telescopes and accessories between Canada and the United States.
We work to have the best selection of astronomy and astrophotography in Canada. We are enthusiasts and work to help others enjoy the hobby that we love so much. We're always interested in helping, reach out with any questions.
